faut with a 672 BGA

2/28/2017 9:05:26 PM

All,
I have an intermittent faut with a 672 BGA where it fails in test but upon applying pressure to the BGA it works.
Clearly there is an issue with the wetting of some Balls causing a poor connection.
My profile looks spot on -
I think I posted this before but never really came to any conclusion ..
What tests can I get carried out to pinpoint the problem?
